VALVE.

Specification of Letters Patent.

Patented Oct. 25, 1910.

I Application filed July 2, 1907. Serial No. 381,922. I

To all whom it mayconcern:

Be it known that we, GUSTAV Scum, and J osarn B. Wrcxs, citizens of the United States, residing at Paulsboro, in the county of Gloucester and State of New Jersey, have invented certain new and useful Improvements' in Valves, of which the following is a specification.

This invention is'a valve or cock which is articularly adapted for use under m h liquid -s or vapor pressures andin refiitions whfii h uire freguent openin and closing, as for 1118011108 or the contro of h drauhc cylinders or the like. 1

The form of the valve, the number and disposition of the a rtures therein, and the material of which it is made will of course depend upon the specific use for which itis intended.

A valve constructed in accordance with our invention is shown in the accompanying drawing, wherein the figure is a central vertical section.

Referring to said figure the valve shown comprises a casi 1 aving an inlet aperture 2 and an out eta erture 3, the particular form of casing s own being provided 'with an integral division plate apertured at 5. The upwardly extending, flange 6 of the casin is internally screw-threaded as shown at to receive the valve-seat member 8 which extends within the casing to the division late 4, making a tight joint therewith. T e inner face 9 of the valve seat member is frusto-conical in form, slightly shouldered above as indicated at 10, and is provided with an a rture 11 extendingthrough said seat in a inement with the casing outlet 3. The valve member 12 is coned in conformit to the seat and is centrally d as s own at 13, the recess being in alinement with the aperture .5. An aperture 14 extends from the recess 13 through the wall of the valve member and is adapted to valve and its stem and to preserve it from corroding liquids. A handle 18 of any suitable type is shown as provided with an indi-. cator 19 .in alinement with the aperture 14.

The construction described possesses many advantages amon which may be mentioned the following: (1 Thevalve is self-adjusting in that the valvemember12 is always forced upwardly against its seat by the fluid pressure applied from below; (2) it is selfgrindingin that the rotation of the valve in one plane against its seat under ressure maintains the two in conformity; 3) it is self-oiling and non-corrodible in that the oil in the pocket 17 serves to lubricate and protect the valve and its stem; (4) nopacking v is required for the stem, a close joint being maintained at the shoulder 10; (5) the valve and its seat constitute an independent memher or attachment separable from the casing and applicable toa casing of any type or form. This permits the valve member to be applied to multiple-way casings having such number of inlet and outlet apertures as may be required, the valve member and the easing being modified if desired by providing two or more outlet apertures therein.

We claim:

1. A valve comprising a casing having an aperture and provided with an interior, transverse, apertured division plate, a threaded valve seat member engaging the aperture .in said casing and extending to said division plate and forming a tight joint therewith, said valve-seat member having an internal shoulder, and a hollow frusto-conical, apertured valve rotatable within said seat-member and carried thereby, said valve having a shoulder engaging the shoulder in said valve-seat member, the lower face of the valve abutting the portion of the apertured division plate surrounding the aperture.

2. A valve comprising a casing having an aperture and provided with an interior, transverse, apertured division plate, a threaded valve seat member engaging the aperture in said casing and extending to said division plate and formin a tight joint therewith, said valve-seat mem er having an internal shoulder, a hollow frusto-conical, apertured valve rotatable within said seatmember and carried thereby, said valve having a shoulder engaging the shoulder in Ya I 073,310
